Overall, I was disappointed. The chemistry between Holmes and Watson is still there, so I'll probably keep coming back, though.
Loved the addition of Amanda Abbington as Mary Morstan. There's a definite chemistry between Watson and Morstan, too (perhaps the fact that Mr. Freeman and Ms. Abbington have been together for years and have 2 kids has something to do with that

). Not looking forward to how she exits "new canon" (because she's not a permanent fixture in the old). I can't believe that "fans" sent Ms. Abbington death threats because they think she's breaking up Johnlock.
As far as the casefic, though, this episode was really lacking. What does everybody want to know? How Sherlock faked his own death. I'm not sure we really get an answer. Yeah, I think somebody read a lot of really bad fan fic and made it legit. And the climax of the other case? You've got to be kidding! Even the worst James Bond is not that camp.
Very nice scene at the beginning between Watson and Mrs. Hudson. Wish there had been more like this.
